Abstract (en)
[origin: US2018355185A1] A coating composition containing a crosslinkable coating composition. The coating system comprises: ingredient A that has at least two protons that can be activated to form a Michael carbanion donor; ingredient B that functions as a Michael acceptor having at least two ethylenically unsaturated functionalities each activated by an electron-withdrawing group; and a catalyst system. In one embodiment, the catalyst system comprises diethyl carbonate, quaternary ammonium hydroxide or quaternary ammonium alkoxide, ethanol and 4-6 wt. % water. In another embodiment, the catalyst system comprises carbon dioxide, quaternary ammonium hydroxide or quaternary ammonium alkoxide, ethanol and 2-4 wt. % water. In certain embodiments, the coating composition optionally further comprising ammonium carbamate (H2NR8R9+—OC═ONR8R9), wherein R8R9 are each independently selected from hydrogen, a linear or branched substituted or unsubstituted alkyl group having 1 to 22 carbon atoms; 1 to 8 carbon atoms; 1 to 3 carbon atoms.
